Case ReportsTrigeminal neuralgia: unilateral episodic facial pain.
Trigeminal neuralgia is a rare cause of episodic unilateral facial pain and often in the initial presentation dental causes need to be eliminated, as it frequently presents in the lower trigeminal divisions. The pain description is characteristic of electric shock-like pain that is light-touch provoked, paroxysmal, and occurring daily; the condition can go into remission for weeks or months, however. The first-line drug is either carbamazepine or oxcarbazepine and has to be started in low doses. ⋯ Patients need to be given information about all treatment options so they can make a decision about treatment.

Questions from patients about pain conditions and analgesic pharmacotherapy and responses from authors are presented to help educate patients and make them more effective self-advocates. This article is about postherpetic neuralgia (PHN), a devastating complication following reactivation of the varicella-zoster virus. The answer offers an explanation for why this pain occurs, and cites literature regarding its incidence and treatment.

Review Case ReportsOlanzapine in the treatment of refractory nausea and vomiting: a case report and review of the literature.
The role of olanzapine in chemotherapy-induced nausea and vomiting (CINV) is supported from randomized controlled trials and national consensus guidelines such as the National Comprehensive Cancer Network. In contrast, the role of olanzapine in refractory non-CINV is limited to case reports/series, retrospective studies, one pilot study, and one randomized controlled trial in patients with major depressive disorder. ⋯ We aim to contribute to the growing evidence supporting the use of olanzapine for refractory non-CINV. Furthermore, we review and summarize the literature regarding olanzapine in the CINV and non-CINV settings.

ReviewFentanyl-induced hyperalgesia in acute pain management.
There are safety concerns with the use of fentanyl, including respiratory depression, nausea, constipation, and possibly opioid-induced hyperalgesia (OIH). The purpose of this review is to evaluate the occurrence and significance of opioid-induced hyperalgesia (OIH) after acute fentanyl exposure. A literature search was conducted from October 1995 through January 2015 using MEDLINE, Embase, and Scopus with the terms hyperalgesia, fentanyl, pronociceptive, acute tolerance, and acute. ⋯ The data on OIH after acute fentanyl exposure are limited and conflicting. Hyperalgesia should be considered in patients with uncontrolled pain despite escalating fentanyl doses, since the possibility of fentanyl-induced OIH exists in the acute setting. Well-designed trials are needed to determine the clinical significance of this phenomenon.

Observational StudyPain indicators for persisting pain in hospitalized infants in a South African setting: an explorative study.
In the developing world, there is a high incidence of human immunodeficiency virus (HIV), gastroenteritis, pneumonia, meningitis, and other inflammatory diseases in infants, the conditions of which may induce persisting pain. The primary objective was to estimate the reliability and validity of the Touch Visual Pain (TVP) scale to measure persisting pain. This prospective observational study was performed in hospitalized 0-3-year-old infants in South Africa. ⋯ Two TVP items were not sensitive to assess pain or distress and were replaced in a revised TVP version. We conclude that our study identified sensitive and specific indicators of persisting pain in hospitalized children under the age of 3 years in a South African setting. Psychometric properties of the revised TVP need to be studied before its use in clinical practice can be recommended.
